As a kilowattrel, Thunk's digestive system starts with his beak. He has no teeth, but can bite down with the sharp edges. He must make a bobbing motion to swallow. His internal flesh is blackish grey.
His long esophagus makes for a perfect opportunity to show off a neck bulge, before the prey slips into the crop. The crop sits at the base of his neck, and is a soft, squishy sack that safely stores treats for a time. He can control whether things come back up from his crop or are pushed further along.
The stomach is like any other and digests things, and he can't bring stuff back up voluntarily.
The gizzard is a weak organ, made for filtering. Occasionally, once the meat is thoroughly liquified, the indigestibles like fur, bones, clothing, and the like are compressed into a pellet, and expelled out the mouth, but usually they pass along with the chyme.
Everything else proceeds as normal, through the small intestine, the large intestine, and then out.

Thunk is a greedy bird and will attempt to swallow any pokemon that he can get his beak around, which tends to be quite a few. He considers them all fish, even the ones he happens to get on land, though he'll usually avoid those with feathers.
His favorite snacks, when he can get them, are electric types, who are often surprised to find that their defenses are useless when faced with Thunk's unique lightning rod ability.
He will absolutely gorge himself silly when food is abundant, and can conjure up his hurricane beneath his gut so that he can continue to waddle long after he should have ceased feeding.
While he sees himself as a top predator, he is not immune to being eaten himself, though he is a tough creature to nail down.
